Kinetic Features

The aim of this study is to develop a biomechanical model and a method to analyze the kinematic and kinetic features of the handcycling activity. By applying this model, the contribution of important factors, like muscles, inertia and weight, on the biomechanics of the handbike is investigated. In order to validate the proposed model, the kinematics and kinetics of the arm have been collected during a handcycling activity in different configurations performed by several subjects. The force applied on the handle has been measured and compared with the one assessed by the model; in addition, the arm muscles activity has been noticed. Moreover, some new indices are defined to describe the performance of handbike athletes in a more precise way to improve their benefits.

Upper Limb Pain

In the United States alone, more than 10,000 spinal cord injuries (SCI) are reported each year. This population depends upon their upper limbs to provide a means of locomotion during completion of their activities of daily living. As a result of greater than normal usage of the upper limbs, proper propulsion mechanics are paramount in preventing injuries. Upper limb pain and pathology is common among manual wheelchair users due to the requirements placed on the arms for wheelchair locomotion. During the wheelchair rehabilitation process following an SCI, an individual is prescribed a wheelchair (WC). The use of a patient-specific computational biomechanical model of WC propulsion may help guide rehabilitation that may improve clinical instruction and patient performance. The overall goal of this study is to develop and refine a computational model that may aide in minimizing shoulder pathology.

Standard Methods

SummaryApplication of the methods of enzyme-kinetic analysis to the results of clotting tests is feasible and can yield useful results. However, the standard methods of enzyme kinetics are not applicable without modifications imposed by the peculiarities of the blood-clotting enzyme system. The influence of the following complicating circumstances is calculated :1. Substrate is not present in excess.2. Only relative measures exist for concentrations of substrate or enzymes.3. Enzymes and substrates are often added together.4. Reagents are not pure.5. Clotting-time is our only measure for clotting-velocity.Formulas are deduced, which makes it possible to recognize the effect of these complications.
